CULTIVATOR.

Specification of Letters Patent.

Patented Jan. 9, 1912.

Application filed April 1, 1911. Serial No. 618,343.

To all whom it may concern Be it known that I, EDWARD J. DAVIS, a citizen of the United States, residing at Grenloch, in the county of Camden and State of New J ersey,-have invented new and useful Improvements in Cultivators, of which the following isa specification.

This invention relates to hand plows and garden cultivators, and it has for its main object to produce a disk implement of this class which, while easy of propulsion and management, shall be sufliciently heavy to engage the soil at a sufficient depth to render the operation thoroughly effective.

A further object of the invention is to produce a wheeled implement of the class described in which the supporting wheels, as well as the disk implement, shall be capable of every useful adjustment and in which simple and eflicient means are pro- 'vided for retaining the parts in adjusted position. I

With these and other ends in view which will readily appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described and particularly pointed out in the claims.

In the accompanying drawings has been illustrated a simple and preferred form of the invention, it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations and modifications within the scope of the claims maybe resorted to when desired.

the drawings,Figure 1 is a side elevation of a device constructed in accordance with the invention. Fig. 2is a top plan view ofthe same. Fig. 3 is a sectional detail view, enlarged, taken on the line 3-3 in Fig. 1. Fig. 4: is a sectional elevation, enlarged, of the upper portion of the body member of the device and related parts. Fig. 5 is a sectional detail View taken on the line 55 in Fig. 4:, and looking in an upward direction, as indicated by arrows. Fig. 6 is a detail view in elevation, showing a small portion of the upper end ofthe body portion of the device, as seen from the opposite side to that exhibited in Fig. 4:. Fig. 7 is a detail view in side elevation of the upper forward part of the casting constituting the body portion of the device including the arm 2 and related parts.

rear arms 2, 3. Near the lower end of the I member 1 is formed a rearwardly extending lug or web 4 with which the handles 5, 5 are connected by means of a bolt 6. At the lower end of the member 1 is formed a horizontal circular disk 7 from which an axially disposed pin or bolt 8 extends downwardly to form a pivot upon which a disk or turn table 9 is mounted for rotation, said disk being retained by means of a nut 10 for the reception of which. the lower end of the pin 8 is threaded,'as shown. I The disk or turn table 9 has an upwardly extending lug 11 for the passage of a set screw 12 adapted to engage the edge of the disk 7, thereby maintaining the turn table 9 in adjusted position. The turn table 9 is provided with a depending flange 13 having a'longitudinal slot 14 for the passage of a supporting member,

such as a bolt 15, which is adjust-able in said slot and with which the disk 16 is associated for rotation in any convenient and well known manner. It will be noticed that the bolt 15 may be moved in the slot 14 to provide for longitudinal adjustment of the disk, while by adjustment of the turn table about its axis, the disk may be placed at any desired angle for engagement with the ground.

' The bodymember 1 is provided adjacent to the disk 7 with a rearwardly extending transversely perforated lug .17 for the passage of a pin or bolt 18. A plate 19 having a slot 20 is provided with eyes 21, see Fig. 3, thus connecting the plate 19 hingedly with the body member 1 for movement in a vertical plane. The slot 20 in the plate 19 extends transversely of the machine, and adj-u'stably associated therewith by means of a fastening member, .such as a bolt 22, is a rearwardly extending arm 23 carrying the" hind wheel 24: which is thus capable of being j moved transversely to any desired point for the most effective operation. Connected with the slotted plate 19 by means of a bolt 25 is a rack segment 26, the arc of which is concentric with the axis of the hinge bolt 18. One of the handles of the machine supports a suitably arranged spring slide 27 engaging the rack segment 26, thereby serving to maintain the hinged plate 19 in adjusted position. The slide 27 may be manipulated by means of an operating rod 28 supported in keepers 29 upon the handle and extending within convenient reach of the operator. Pivotally supported upon the front arm 2 of the body member by means of a pin or bolt 30 is an angle plate 31 having its rear edge notched to form an arcuate rack 32 disposed for movement in a vertical plane and adapted to be engaged by a slide 33. The slide 33 has a pin 34 guided in apertured lugs 35 upon the arm 3 and engaged by a suitably arranged spring 36 whereby it is held in engagement with the arcuate rack 32. The slide 33 is operable by a suitably supported and guided rod 37 that extendswithin convenient reach of the operator.

Pivotally mounted upon an approximately vertical pin or bolt 38 associated with the angle plate 31 isa plate 39 having a forwardly extending arm 40 carrying at its front "end a vertically disposed tubular sleeve 41 wherein a shaft 42 carrying at its lower end'a spindle 43 is mounted for rotation, said spindle serving to support the front Wheel 44. 'The shaft 42 carries; at its which is. connected by a link rod 46 with an arm 47 that extends laterally from the angle plate 31. The rear edge of the plate 39, which is arcuate in shape and notched to present a rack bar 48, is guided beneath overhanging lugs 49 of the angle plate 31, and is adapted to be engaged by the springactuated slide 50 supported upon said angle plate'and adapted to be actuated by means of an operating rod 51 which extends within convenient reach of the operator. 5

It will be observed that by releasing the slide 33 from engagement with the rack upon the angle plate 31, the latter may be tilted to raise or lower the front wheel 44. By releasing the slide 50 the plate 39- may be turned about its axis for the purpose of effecting lateral adjustment of the wheel, l

and when the latter adjustment ismade, the shaft 42 will be simultaneously oscillated by the link 46, connecting the arms .45 and 47 to keep the wheel straight in the line of progress. 7

The upper end of the arm 3 of the body member 1 is connected by braces 52 with the handles '5 which are thus braced and rein-.

forced. The front and rear wheels are preferably flanged, as clearly indicated in' Fig. 2 of the drawings, thus enabling them to, hug the ground and at the same time to prevent lateral displacement of the, machinewhen itis'progressing in operation.

. an upwardly extending lug and a downwardly extending slotted flange, a set screw ted plate having eyes-hingedlyfassociated one of the handles.

"known construction may be substituted for.

the disk herein illustrated.
